5.1.11- FF: Fault log display
Chronological display of the faults that have occurred during system op-
eration.
Under the symbol FF appear two numbers x/y indicating respectively the
ault displayed and the total number of faults present; to the right of these
numbers is an indication of the type of fault displayed.
The + and – keys scroll through the list of faults: pressing the – key goes
back through the log and stops at the oldest fault present, pressing the +
key goes forward in the log and stops at the most recent fault.
The faults are displayed in chronological order starting from the one that
appeared farthest back in time x=1 to the most recent x=y. The maximum
number of faults that can be shown is 64; when that number is reached,
the log starts to overwrite the oldest ones.
This item on the menu displays the list of faults, but does not allow reset.
Reset can be carried out only with the dedicated control from item RF on
the TECHNICAL ASSISTANCE MENU.
The fault log cannot be deleted with a manual reset, by switching off the
appliance, or by resetting the factory values, unless the procedure de-
scribed above has been followed.

5.3 - Setpoint Menu
From the main menu, hold down simultaneously the "MODE" and "SET"
keys until "SP" appears on the display (or use the selection menu pressing
+ or -).
The + and – keys allow you respectively to increase and decrease the
plant boosting pressure.
Press SET to leave this menu and return to the main menu.
The range of adjustment is 1-5 bar (14-72 psi).
5.3.1 - SP: Setting the setpoint pressure
Pressure at which the system is pressurised.
The pump restarting pressure is linked not only to the set pressure
SP but also to RP. RP expresses the decrease in pressure, with
respect to "SP" caused by the pump starting.
For example: SP = 3,0 [bar]; RP = 0,3 [bar];
During normal operation the system is pressurised at 3.0 [bar].
The electropump restarts when the pressure falls belowai 2,7 [bar].
